<question heading="Connect to Listening OpenOffice">How to connect to a already listening OpenOffice?
<p>You can start a OpenOffice in listening mode with e.g. this command:</p>
<p>ooffice -accept=&quot;socket,host=localhost,port=9000;urp;StarOffice.ServiceManager&quot;</p>
<p>This commandline starts OpenOffice listening on port 9000</p>
</question>

<p>This method connect to a listening OpenOffice.</p>
<listing>// You should import following classes:
// import com.sun.star.beans.XPropertySet;

// import com.sun.star.lang.XMultiComponentFactory;
// import com.sun.star.uno.UnoRuntime;
// import com.sun.star.uno.XComponentContext;

    // You will need these Objects often, so define them global...
    Object desktop = null;
